Excellent ...

Very nice explanation.

What you get in volume, you lose in speed, right ? It's a cool mechanism though

thank you so much!

Great for using as an office desk fan and when you're watching TV or reading

VERY NICE VEDIO, NICE EXPLAINATIO, NICE VOICE QUALITY.

Is it possible to run fan in reverse and make it act as vacuum cleaner?

If this structure were outside and swiveled towards the wind, could the lower mount fan plus inducted air and also the entrained air produce enough energy so that a ducted air generator makes more electricity than the mount fan? Thinking of this as a small to medium device. Home or RV solutions. I'm thinking about the camping angle. Too much is about solar panels but hybrid electrical input should equalize weather changes and power needs.

Is it possible to make such fan in large size? say square share 4x4 feet?

The major problem with your presentation is the words bladeless fan, you and many others are trying to give a false impression. Click bait. Nothing in your presentation is remotely new or noteworthy all of this phenomena has been well understood for many years. You only have the most limited knowledge of fluid dynamics.

Aerofoil wings work by having a flatter underside which causes less acceleration of the air, not by tilting them. I'll go to someone who knows how it works for an explanation.

I have the basic understanding of aerodynamics and this video explains it perfectly. Thanks for sharing 👌👍

Thank you for explaining. This is by far the best explanation I have seen so far. Does the entrained airflow help with lowering the low pressure area? making the unducted airflow stronger?

Maybe,self propelled wind turbine blades , then you can combian centrificail force also

Are they using compressed air to start it up or injecting fuel like a jet engine for added thrust?

If it works In air, can I assume It will work in water? Basically a ram jet? Anybody ? Got any thoughts on that or how about applying it to a vertical windmill

"bladeless" fans have fan insiide. so it is just less effective construction. th-cam.com/video/6Uqfy4n9V00/w-d-xo.html

The sad part is. You're doing it all wrong. If only I could show you my work. The geometry and compression of the air in a tornado are more efficient than what I have on the whiteboard.

Lo ví traducido al español Te agradezco haberme explicado dónde está el truco, al parecer éste tipo de turbina o complemento de turbina promete mucho para las aerolíneas, que sus aviones son de motores de rotores coaxiales osea el rotor del turbo reactor está por fuera y el rotor de los ventiladores enormes que vemos dentro de las cáscaras están por dentro del turbo reactor, y demasiado texto ya muchos se la saben pero algunos quienes me lean no entenderían… pero quienes entiendan ésto promete mucho reemplazando por completo esos ventiladores pesados y esos enormes cascarones osados por unos más funcionales y también reemplazando los turbo reactores por unos más pequeños ó por motores así como del que llevan en la cola del avión que no me acuerdo cómo se llama

great job! thanks for sharing this information

Now that was Very Interesting and Well Explained

It is *Coandă* Effect, named after Romanian inventor Henri Coandă. Not Calendar ~. 😆

Very interesting video. The bladeless fan multiplies the air quantity flow. For it to work well with an aircraft the air must be accelerated at the exit and not increased in pressure. although it would work ok with a slower flying aircraft. It would be interesting to see a comparison with a conventional electric ducted fan (EDF) showing power consumption and thrust between both bladeless and conventional fans.

I seemed to have missed the part that explains the flaws. LOL

This information is partially incorrect. An aerofoil cannot be acimetric in design as it will create an equal amount of pressure to each surface resulting in no lift ie lift generated due to a high pressure area under the wing moving towards a low pressure area above the wing. Changing the angle of attack won't create lift.

very nice simple and clear thanks

Greetings ladies and gentlemen of this comment section. As a formula student racing car enthusiast. I was wondering if a blade less fan can effectively suck more air than a bladed fan ? We intend to use a fan on our upcoming competition car, but we’re not too sure whether the blade less far will work as well as a bladed fan. Thank you in advance

Thank you ❤️

beautifully made video, with clear explanation. Thank you ever so much

Perfect explanation! It is always important the way how you teach the complex subject to the audience. Thank you!

Thank you SO MUCH!

thank you. could one be designed than run from the convection off a tea light? i built one from tin cans and ran it on ethanol for some interesting results.

what happened you killed it on your first video why stop making them

very good

You are only correct from 7:30 onwards.

Excellent explanation

So would you say a "bladless" fan puts out air better that a normal one?

What about the constant back pressure the compression fan has to fight to maintain and create, would that require a constant high amperage demand from the power supply? Wouldn't this be a major problem to overcome when trying to implement this into aircraft when weight is a major factor for battery system needed for sufficient flight time?

May I join this fan club

Are you not entrained?!

now that's alot of air😅😅😅

i saw jetoptera and fell in love

Well explained. Thanks

There's no such thing as a bladeless fan! it's a ducted fan! the blade is just hidden.

Thank you sir for the wonderful explanation

GUI is broke on the project. Tried running it today

Great Explanation, simple and clear, Thank you !

Hello . My Lord Boss and I invented a super revolutionary engine for any type of fuel, including synthetic methanol for negative CO2 emissions and HYDROGEN for ZERO emissions, obtaining much more efficiency than a current engine and greater than batteries and also fuel cells. fuel that are used with hydrogen and electric engines, a novel thermodynamic cycle with more than 75% efficiency, only two main moving parts, a power / weight ratio greater than 13 KW / Kilo, everything can be aluminum except main shaft and screws, uses no liquid coolant only air, uses very little lubricant that can be used from the center through the seals to lubricate everything, the speed of the seals or segments is 7 times less than in any engine, can be extrapolated to any power without losing any features, is under international PCT patent process. Very easy to manufacture 100% with current basic technology, all its main moving parts mounted on commercial bearings, the useful life is up to 30,000 hours with very low maintenance, almost zero and more than 70 additional advantages.... As an example: Motors of 60 kilos of 1000 Kw can be made very compact without useless space. th-cam.com/video/5WBoIzC0azY/w-d-xo.html

Shouldn’t the surface of the exit air be curved like a typical airfoil to increase lift?
